21 Top Building Toys for 3-Year-Olds

I have often referred to my son as our “little engineer” because he loves building, designing, and problem-solving. If you, too, have a little one who seems to be a budding engineer, you will love these building toys for 3-year-olds. Each of these building toys has been specifically chosen for being age-appropriate and highly-rated, and many have been personal hits in my own home. Building toys are especially wonderful gift choices because they will keep your 3-year-old engaged in creative, educational open-ended play. They are also a good investment because they will grow with your child beyond the preschool years.
